The existence of money as a means of buying or selling goods and services dates back to at least 3000 B.C. , when the Sumerians began using metal coins in place of bartering with barley. The use of paper money began in China during the seventh century, but its uncertain value, as opposed to the more universally accepted value of gold or silver coins, led to widespread inflation and state bankruptcy. It was not until 1658, when Swedish financier Johann Palmstruck introduced a paper bank note for the Swedish State Bank, that paper money again entered circulation.
The first paper money in what is now the United States was issued by the Massachusetts Bay Colony in 1690. It was valued in British pounds. The first dollar bills were issued in Maryland in the 1760s. During the American Revolution, the fledgling Continental Congress issued Continental Currency to finance the war, but widespread counterfeiting by the British and general uncertainty as to the outcome of the revolution led to massive devaluation of the new paper money.
Stung by this failure, the United States government did not issue paper money again until the mid 1800s. In the interim, numerous banks, utilities, merchants, and even individuals issued their own bank notes and paper currency. By the outbreak of the Civil War there were as many as 1,600 different kinds of paper money in circulation in the United States—as much as a third of it counterfeit or otherwise worthless.
Realizing the need for a universal and stable currency, the United States Congress authorized the issue of paper money in 1861. In 1865, President Lincoln established the Secret Service, whose principal task was to track down and arrest counterfeiters. This early paper currency came in several different types, designs, and denominations, but had the common characteristic of being somewhat larger in size than today's money. It was not until 1929 that the current-sized bills went into circulation. In 1945, the government stopped printing bills in denominations greater than $100, and in 1963, they stopped printing silver certificate bills with the assurance that the dollar amount was available "…in silver payable to the bearer on demand."
With paper money, the materials are as important as the manufacturing process in producing the final product. The paper, also known as the substrate, is a special blend of 75% cotton and 25% linen to give it the proper feel. It contains small segments of red and blue fibers scattered throughout for visual identification. Starting in 1990, the paper for $10 bills and higher denominations was made of two plies with a polymer security thread laminated between them. The thread was added to $5 bills in 1993. This thread is visible only when the bill is held up to a light and cannot be duplicated in photocopiers or printers.
The inks consist of dry color pigments blended with oils and extenders to produce especially thick printing inks. Black ink is used to print the front of the bills, and green ink is used on the backs (thus giving rise to the term greenbacks for paper money). The colored seals and serial numbers on the
The design of the front and back of each denomination bill is hand tooled by engravers working from a drawing or photograph. Each engraver is responsible for a single portion of the design—one doing the portrait, another the numerals, and so on.
The portrait on the face of each bill varies by the denomination. George Washington appears on the $1 bill, Abraham Lincoln on the $5, up to Benjamin Franklin on the $100 bill. These persons were selected because of their importance in history and the fact that their images are generally well known to the public. By law, no portrait of a living person may appear on paper money.
In 1955, Congress passed a law requiring that the words "In God We Trust" appear on all U.S. currency and coins. The first bills with this inscription were printed in 1957, and it now appears on the back of all paper money.
Starting in 1990, very small printing, called microprinting, was added around the outside of the portrait. This printing, which measures only 0.006-0.007 inches (0.15-0.18 mm) high, repeats the words "The United States of America." It appears on all paper money except the $1 bill.
In the United States, all paper money is engraved and printed by the Bureau of Engraving and Printing, which is part of the Department of the Treasury of the federal government. The Bureau also prints postage stamps, savings bonds, treasury notes, and many other items. The main production facility is located in Washington, D.C., and there is a smaller facility in Fort Worth, Texas. Every day, the Bureau prints approximately 38 million pieces of paper money. About 45% of this production are $1 bills and 25% are $20 bills. The rest of the production is divided between $5, $10, $50, and $100 bills. Although the $2 bill is still in circulation, it is rarely used, and therefore is rarely printed. Each bill, regardless of its denomination, costs the government about 3.8 cents to produce.
There are 65 separate operations in the production of paper money. Here are the major steps:
Anything as important as money requires strict quality control standards. Flawed money is bad money and cannot be placed into circulation. In addition to the many inspections that occur during the printing process, the raw materials are also subject to strict inspections before they are used. The inks are tested for color, viscosity (thickness), and other properties. The paper is produced by a single manufacturer in a secret, tightly controlled process. The paper is tested for chemical composition, thickness, and other properties. It is illegal for anyone else to manufacture or possess this specific paper.
The finished bills are also tested periodically for durability. Some bills are put through a washing machine to determine the colorfastness of the inks, while others are repeatedly rolled into a cylinder and crushed on end to determine their resistance to handling. It is estimated that a bill can be folded and crumpled up to 4,000 times before it has to be replaced.
Despite the use of high-quality paper and inks, the average life of a $1 bill in circulation is only about 18 months. Other denominations last somewhat longer. When a bill has been defaced, torn, or worn to the point where it is no longer identifiable or useable, it is taken out of circulation and returned to the federal reserve banks for destruction by shredding. Some of this shredded money is recycled to make roofing shingles or insulation. Money that is damaged or otherwise flawed during the printing process is shredded at the Bureau of Engraving and Printing plants.
For U.S. paper money, the future has arrived. Starting in 1996, the Department of the Treasury began issuing $100 bills with a new front and back design and several new security features designed to make counterfeiting more difficult. Other new bills in descending denominations will be printed at the rate of one new denomination per year.
The new bills use the same paper and are the same size and color as today's bills. Multicolor images, such as are commonly found on European currency, were not used because they were too easy to duplicate with color photocopies and printers. The image of Benjamin Franklin still appears on the front of the new $100 bill, although his portrait is larger and is shifted to the left. A watermark, formed by reducing the thickness of the paper during manufacture, has been placed to the right of the portrait and shows a second image of Franklin when the bill is held up to the light. The imbedded security thread is also still there, although now it has been treated to glow red under ultraviolet light. The position of the thread varies depending on the denomination of the bill to prevent the counterfeiting practice of bleaching the ink off lower denomination bills and reprinting them as higher denominations.
Other new features include concentric fine lines behind Franklin's head on the front and behind the image of Independence Hall on the back. These lines are so fine that they are extremely difficult for copiers or printers to duplicate without blurring them into a solid background. Microprinting, which was introduced in 1990, is used in two places on the new $100 bill; the words "USA 100" appear within the lower left-hand numeral 100, and the words "United States of America" run down the lapel of Franklin's coat.
Perhaps the most high-tech feature is a special color-shifting ink which is used to print the numeral in the lower right-hand corner. When viewed from head on, this ink appears green, but changes to black when viewed from the side.
Lower denomination bills will have many, but not all, of the security features present in the new $100 bills. The highest level of protection was given to the $100 bill because it is the largest denomination being printed. It is also the most common bill in circulation outside the United States, and hence, is frequently counterfeited in other countries.
Some of the security features originally proposed for the new money—such as holograms, plastic films, and coded fiber optics—were not used for this latest change because they represented too great a departure from the current money or because of potential technical problems.
Looking further into the future, paper money may eventually be replaced by electronic money that is downloaded onto plastic "stored value" cards from an ATM or computer. Each card would have a computer chip memory, and the money would be electronically transferred through a card reader to make purchases.
